Using C code in the heat equation

The code for this exercise is located under interface/c.

~/hpc-python$ cd interface/c

Using cffi

The files evolve.h and evolve.c contain a pure C implementation of the
single time step in heat equation. The C implemention can be built into a
shared library with the provided Makefile by executing make
command. Use cffi for utilizing the library function instead of the Python
